      Yes! This is ‘it’, exactly.

      It seems each new ‘robo call’ comes from a different (spoofed) phone number. So regardless of how helpful the article above is (and it’s very helpful) it is useless against this new random fake number generation of the latest phone invaders.

      Being able to block an area code would, at least, be somewhat helpful. Though when the fake numbers generated have one’s own area code, then we’re back to square one :(
